Marlboro Ducati's Casey Stoner has been diagnosed with mild anaemia and slight gastritus after undergoing a battery of tests at Dr Ting's Fremont Clinic over the past week.

The Australian former MotoGP World Champion was left feeling weak after the last three races had been phyiscally sick into his helmet more than once. He is undergoing treatment which will continue for the foreseeable future but doctors say he will make a full recovery.

“I have been in USA until Saturday to do all the tests. First of all I’d like to thanks all the Doctors involved in this, Dr. Ting and Dr. Tuan in the Fremont Surgery Center, Dr. Macchiagodena, Dr. Catani, Dr. Ceccarelli and of course my physiotherapist Freddy," said Stoner.

"Hopefully step by step I will feel better with their indications. I still don’t feel like I am 100% but the biggest problem now is the ribs that are very painful after the crash in the USA GP Qualifying. It will be probably another hard weekend, but as always, we will do our best to stay as much as possible close to the lead of the Championship."
